Book excerpt: This book represents a high-water mark in our understanding of the history of the Kuki-Chin branch of Tibeto-Burman. Nearly 1400 reconstructed cognate sets are presented, at various taxonomic levels: Proto-Kuki-Chin, Proto-Central-Chin, Proto-Northern-Chin, and Proto-Maraic. Special attention is paid to the subgrouping of this highly ramified family, based on the patterns of shared phonological innovations which the various languages display.
